WebA chromatid (Greek khrōmat- 'color' + -id) is one half of a duplicated chromosome. Before replication, one chromosome is composed of one DNA molecule. In replication, the DNA molecule is copied, and the two molecules are known as chromatids. [1] WebFeb 11, 2011 · Chromosome and chromatid are closely related structures that are made from DNA molecules. Chromosomes contain genetic information in the form of specific DNA sequences or genes. A single strand of DNA is called a chromosome and two chromatids will form a single chromosome.

WebIn summary, chromatids are the two copies of a chromosome that are formed during DNA replication and are visible during prophase.
